Answer: a. Dendritic
Explanation:
A dendritic drainage pattern is the most common form and looks like the roots of trees branching pattern. It is a drainage pattern in which streams branch in many directions randomly at different angles as well. It develops in regions that have underlying homogeneous material. This means the subsurface geology has a similar resistance to weathering resulting in no seeming control over the direction the tributaries take. It is produce in streams that receive several tributaries that are fed by smaller ones. Tributaries link up a larger stream at acute angle ( angle less than 90 degrees). It can be indicated when streams flow across horizontally and complex crystalline rock/homogeneous strata help in resisting erosion uniformly.
There would be no water in the earth to drink, and as we all know that water is the most important essence in our daily lives.
Answer:
A cultural hearth is the origin location of the cultural trait being spread through diffusion. Therefore, the role it plays in the diffusion of a cultural aspect is being the starting point. From that point on, it will either spread as hierarchical diffusion, stimulus diffusion, relocation diffusion, or expansion diffusion.
